WHAT DOES THE GYRO DO?
The gyro is an essential component in many RC helicopters. Gyros in RC helicopters are most commonly used to control unwanted movement on the yaw axis. When an RC helicopter rotates on its yaw axis, the direction the nose points (the heading) changes. The yaw gyro’s job is to sense any undesired rotation around the yaw axis (clockwise or counter clockwise rotation when viewed from above), and to automatically correct the orientation of the RC helicopter. Without a yaw gyro, even if the RC helicopter was trimmed out to fly straight initially, it would eventually begin to drift and rotate right or left. Normal maneuvering of the RC helicopter and external foRCes can result in undesired yaw rotation. When this occurs, the gyroscope senses this change in yaw and corrects it. This results in stable flight for the RC helicopter and no undesired changes in yaw.
